Morgan Stanley is saying that Apple may be expanding its line beyond just Apple TV to an actual “Smart TV”. “Checks in Asia suggest Apple is working on a Smart TV prototype,” analyst Katy Huberty said in a note to investors on Friday. She also suggested that such a TV could help create a whole new Smart TV category. While there are already connected TVs that some manufacturer’s advertise as being “smart,” Huberty thinks Apple’s could include “TV/Video content, gaming, DVR as well as other features like apps and FaceTime.” By 2013, such a device could earn Apple roughly $4 billion for every 1% of the TV market it grabs, Huberty said.
